This poses an ethical problem, because we may be causing these animals uenaernscsy suffering. Scientific eemxiatornpiten, though controversial, gives us some clues. Tests on himret crabs show that they’ll leave an undesirable shell if they’re zapped with electricity. But stay if it’s a good slehl. And octopi that might originally curl up an injured arm to protect it, will risk using it to catch prey. That suggests that these animals make value judgments around ssneroy input, instead of just ratcenig reflexively to harm. Meanwhile, crabs have been known to repeatedly rub a spot on their bodies where they’ve reeviced an electric shock. And even sea slugs filnch when they know they’re about to rceieve a noxious stimulus. That means they have some memory of physical sensations.

Original Text

This poses an ethical problem, because we may be causing these animals unnecessary suffering. Scientific experimentation, though controversial, gives us some clues. Tests on hermit crabs show that they’ll leave an undesirable shell if they’re zapped with electricity. But stay if it’s a good shell. And octopi that might originally curl up an injured arm to protect it, will risk using it to catch prey. That suggests that these animals make value judgments around sensory input, instead of just reacting reflexively to harm. Meanwhile, crabs have been known to repeatedly rub a spot on their bodies where they’ve received an electric shock. And even sea slugs flinch when they know they’re about to receive a noxious stimulus. That means they have some memory of physical sensations.
